I managed to get my 2g iphone stuck on the apple logo,
and i looked arounf on the internet and couldnt find anywhere that told me what to do!
I even looked on these forums and there was nothing!!

so i thought if answer my own question for all others out there with the problem!!
if the iphone gets stuck on the apple logo then hold the home anf power buttons untill it resets
if it is still stuck
hold those 2 buttons untill the connect to itunes logo appears!!
this may require it resetting a number of times!!
it did with me
